The main activities are:

• Site remediation: soil and groundwater remediation
• Soil treatment: Envisan has its own certified independent soil recycling centres
• Disposal technologies: Envisan offers complete concepts for a state-of-the-art construction and management of landfills, lagoons and tailings ponds
• Treatment of dredged sludge: dewatering, treatment, conversion into recycled materials and immobilisation belong to the applied techniques

The integration of these various activities within the company enables Envisan to offer a solution to every environmental problem, as diverse and complex as it may be. As a matter of fact, on several national as well as international occasions, Envisan has proven to be a serious candidate for complex remediation and rehabilitation projects like "brownfields".

In order to further enhance its professionalism, experience and relationship with its international dredging mother company Jan De Nul Group, Envisan is nowadays focusing its efforts on European project opportunities with particular attention for those countries which recently joined the European Union or will soon become a member. Therefore Envisan can rely on the commercial activities of its own international cell, the network of representatives of Jan De Nul Group as well as on other international foreign partners. Not only the mobility of its collaborators, but also the mobility of its advanced technologies like thermal desorption, immobilisation and mechanical dewatering are important key factors of Envisan's international success.
